Police are investigating at least 11 violent incidents on the opening night of the Wisconsin State Fair has resulted in the arrest of a 16-year-old African-American who reportedly told investigators he targeted whites. As described by cops, the “offenders…were described as African American. The victims were either White or Hispanic.”

On opening night of the State Fair, 31 people were arrested and at least 11 people were hurt. The West Allis Police Department has said race was a factor in the 11 violent incidents it's investigating.

Witnesses told the Journal Sentinel, that around closing time of 11 p.m., dozens to hundreds of black youths attacked white people as they left the fair, punching and kicking people and shaking and pounding on their vehicles. Witnesses said the attacks appeared to be unprovoked and racially motivated.

"You could just tell they were after white people. That was the main thing. If you were white, they were coming after you," said Jon Stikl of Oak Creek. "We noticed a group of five to 10 young black males run up and jump a young white male for no other reason then him being white," Stikl said.

They knocked him to the ground, and then a group of 15 black men kicked and stomped on him, Stikl said. "My wife's brother jumped out of the car - his natural reaction was to try to break it up. Before you knew it, five or 10 guys were on him and started punching at him. My wife was able to pull him back in the car. So now they surrounded my car and just started punching through the windows, kicking and shaking the car, screaming racial things."

Andrew J. Coleman, a recent University of Wisconsin-Milwaukee graduate, said he and a friend were attacked about 10:30 p.m. after they left the fair through the gate off S. 84th near the Pettit National Ice Center. "I just heard footsteps behind me and I turned around and I got hit in the face. There were six or seven just beating on me," said Coleman, who has a sore jaw from the punches. His friend was stomped on and his sneakers stolen, said Coleman, of Milwaukee."It looked like they were just going after white guys, white people," said Norb Roffers of Wind Lake in an interview with Newsradio 620 WTMJ. He left the State Fair Entrance near the corner of South 84th Street and West Schlinger Avenue in West Allis. "They were attacking everybody for no reason whatsoever."

"It was 100% racial," claimed Eric, an Iraq war veteran from St. Francis who says young people beat on his car. "I had a black couple on my right side, and these black kids were running in between all the cars, and they were pounding on my doors and trying to open up doors on my car, and they didn't do one thing to this black couple that was in this car next to us. They just kept walking right past their car. They were looking in everybody's windshield as they were running by, seeing who was white and who was black. Guarantee it."

Eric, who asked Newsradio 620 WTMJ not to use his last name, talked about the incidents that happened as he, his wife and a neighbor left the fair Thursday.

"We exited at the Schlinger and 84th exit, and we walked south about a block, and then went up and got our car, came back up and around down Schlinger. When we made a left hand turn, we were stopped in traffic. I looked toward the bridge, right before you get on the freeway, and all I saw was a road full of black kids, jumping over people's cars, jumping on people's hoods, running over the top of them."

A witness told WTMJ that as he worked in a kiosk at the State Fair Midway, he saw what he described as "a Riverwest type mob. Easily between 50 - 100 kids all under 18 and all African American. They were running around knocking people over (young kids and adults), looting the Midway games (stealing the prizes), starting fights." The witness, who asked not to be identified, couldn't say for certain if only white people were being attacked.
